Bawoos are a B gear's bread and butter. These are mainly used for two of B gear's skills: ABM and GBM. The firing pattern of these missiles is 2x1. They have an Accuracy/Probability of 85.10% and a Reattack time of 4.00 seconds. They have comparatively low Reattack damage due to the high Reattack time required. However, Bawoos surpass any other missile available in the game in Attack power. The higher the level of the Bawoo, the greater its damage power. Pair this attack power with a B gear's GBM and ABM skills and you have yourself a missile that could almost kill any enemy with a single hit! This advance weapon is very effective against A gears.
Also known as "Hawk" in the game, these have a firing pattern of 4x1, reattack time of 1.40 seconds and a base Probability/Accuracy of 90.20%. This makes it a great advance weapon for camping gates during Mother Ship, Strategic Point and OutPost wars. It is advisable to enchant Hawks with Reattack, upto e10 or e11 at least, and watch your enemies perspire under pressure from the barrage of missiles you will hurl at them!
